Concept explainers
The annual interest rate r, when compounded more than once a year, results in a slightly higher yearly interest rate; this is called the annual (or effective) yield and denoted as Y. For example, $1000 deposited at 5%, compounded monthly for 1 yr (12 months), will have a value of
For Exercises 41-48, find the annual yield as a percentage, to two decimal places, given the annual interest rate and the compounding frequency.
Lena is considering two savings accounts: Western Bank offers 4.5%, compounded annually, on saving accounts, while Commonwealth Savings offers 4.43%, compounded monthly.
a. Find the annual yield for both accounts.
b. Which account has the higher annual yield?

The specifications call for the case to be made of sheet metal that costs $90/m2, the top to be made from sheet metal that costs $45/m2 and the wall to be made of sheet metal that costs $80/m2. If you want to minimize the cost to make the storage house, how much would you end up spending to build the tank?arrow_forwardCalculate the max value of the directional derivatearrow_forward
